Of course, the drone business would not last long if there wasn’t any money to be made.
Maybe not in general but sometimes it’s so obvious that you are probably thinking, “Why did I not think of this before?”. Real estate agents can make beautiful movies of the houses/apartments/business premises that they want to put into the market. If you pay attention, you will see drone footage daily in the news or in movies/series. A drone can follow the progress of a construction project in real time and the stakeholders (owner, architect, contractor) can view the images or the live streaming from the office (wherever in the world).
Anyway, once a drone can bring a cement bag of 25 kg at height in construction, we are dealing with no less than, and I choose the word carefully, a revolution!
